A council spokeswoman said: “A group from the travelling community arrived on Moor Park on Sunday 9th September. Officers have attended to speak to them and welfare checks will soon be carried out by colleagues at Lancashire County Council.

“Eviction proceedings against the group will be commenced should the families fail to leave the site voluntarily.

“This is a large public park and it’s hoped disruption to local residents, businesses and park users will be minimal.”
